Use build-in InfiNet Wireless Device features. These features allow
evaluating current channel/signal quality and perform precise antenna
alignment
Omni-directional and sector antennas have a wide radiation diagram width, thus
usually they either do not require a very precise alignment or it is just not
necessary due to radio link requirements.
Antenna polarization must be taken into consideration while installation. In most
cases omni-directional and sector antennas have a vertical polarization.
Directional antennas can be installed either with vertical or horizontal
polarization. Please check a corresponding labeling on the antenna and address
to the antenna technical documentation.
Precaution measures
Before you start the installation please read this section very carefully.
Antennas are installed on the roof tops or on the building walls. This work must
be accomplished only by personnel having special skills and experience in this
area.
Antennas and cables are electric conductors. Incidental electrostatic strikes may
occur during the system installation. This can lead to equipment damaging or
may hurt the personnel. While installing or changing the elements of the
antenna-feeder system one must make sure that open metal parts are
temporarily grounded.
Do not install the antenna close to the electric power lines. Antenna and antenna
pole have to be installed in such a way that while their assembling,
disassembling and repairing they did not have any contact with power lines.
Basic precaution measures that must be fulfilled during the installation are the
following:
Do not stay on the roof top in windy or rainy weather, during the
thunderstorm or when the working zone is covered with snow or ice
Do not touch the antennas, antenna poles, cables and lighting arrestors
during the thunderstorm
Antenna placement should not be close to electric or telephone lines.
Safe distance is a distance that is a sum of the two antenna poles
heights and antenna height
Antenna cable must be grounded at all times (not relevant for 5000-M
modifications)
In case of failure any manipulations with the equipment are allowed
to skilled personnel only.
